PerPic Camera Controls: Exposure, Focus, White Balance, Zoom and More

PerPic's current App Store listing describes several manual-style camera controls: exposure, white balance, focus, zoom, grid and level. These controls give users more control over the capture environment than a basic selfie timer.

Exposure

Exposure affects how bright or dark the captured image appears. In difficult lighting, manual exposure control can help prevent a bright background from making the subject too dark or a bright face from becoming overexposed.

White balance

White balance influences the color temperature of a photograph. Indoor lighting, daylight and mixed lighting can produce different color casts. A white-balance control can help maintain a more intentional appearance.

Focus

Focus determines which area of the scene appears sharp. For self-portraits, stable framing and consistent subject distance can make focus easier to manage.

Zoom

Zoom changes framing without requiring the phone to be physically moved. Because camera hardware and available zoom ranges vary by iPhone model, the practical result can differ between devices.

Grid and level

Grid and level tools help with composition and alignment. A grid can make it easier to keep the horizon or subject placement consistent, while a level indicator can help avoid unintentionally tilted frames.

Feature availability should be checked against the current PerPic version and the user's iPhone model.

Composition tools

Grid and level controls are useful when the phone is mounted on a tripod or placed on a stable surface. They can help keep horizons straight and subject placement consistent between frames.

Lighting controls

Exposure and white balance matter when the scene contains strong window light, warm indoor bulbs or mixed illumination. These controls allow a photographer to make a more deliberate capture rather than accepting every automatic decision.

Device differences

Actual camera behavior depends on the iPhone model and current iOS version. A control exposed by the app can still interact with hardware limitations, available lenses and the operating system. Check the current app version on the device when evaluating a specific control.
